Height

Enter your height in centimetres. Along with your weight, height is one of the key inputs to BMR prediction equations such as the Henry and Mifflin-St Jeor formulas .

Weight

Enter your weight in kilograms. This value is used, along with your other details, in the weight-based equations that estimate your basal metabolic rate .

Activity level (count)

Choose Sedentary or light activity if your day is mostly sitting or standing with little movement; Active or moderately active if you regularly add moderate to vigorous activity to a light routine; Vigorous or vigorously active if you do strenuous work or exercise for several hours regularly.
